Microsoft became the first publicly traded company to surpass a $3 trillion market capitalization during 2024.
Microsoft crossed the $3 trillion level during trading on January 24, 2024, briefly becoming the world’s most valuable company by market capitalization. Its valuation was driven by strong cloud growth and investor enthusiasm about its artificial-intelligence partnership with OpenAI.
Microsoft’s Azure cloud business became a major part of the company’s growth story, alongside software products such as Windows, Office, and the company’s business services. The company’s AI strategy also included integrating generative AI tools across its products.
Apple had been the first company to reach $3 trillion in 2022, so Microsoft’s milestone is often misstated as the first ever. Microsoft was the first to surpass that level during the 2024 competition for the top market-cap ranking.
